Although the SESTAT questions, in general proved to be quite reliable, the reinterview data indicated
this item was among those with the highest variance, possibly because the list of response categories
was not read in CATI by each survey contractor. "Suitable job not available" was the most unreliable
category. Item nonresponse was one percent or less for each survey.
